Read time 5 minutes

Exchange Database work under the settings of an Exchange Server and synchronize the mailboxes to keep the data consistent and available. But a database is not limited to its parent Exchange Server only. You can restore a database to a new server with better features and security. There are some manual methods that can help you in restoring the database without making changes in the mailbox. But they require a certain level of expertise to complete securely.

In this article, we will talk about restoring databases from one Exchange Server to another with the manual as well as the automated methods.

Restore database using portability method

It is one of the most efficient methods to restore the Exchange database to another server. Database portability allows you to restore the mailbox database of any Exchange server to the target server easily. Database Portability feature is available for almost every Exchange Server, including Exchange 2007, 2010, 2013, and 2016.

Before starting the database migration from one server to another with the Database Portability method, there are some things that you need to know.

Things to know before moving the data

Steps to move database to a new server

  1. Open Exchange Management Shell.
  2. Make sure the data you want to move is in the clean shutdown state. If it isn’t, then perform a soft recovery.
    ESEUTIL /R <Enn>
  3. Now, use the following syntax to create a database on the new server.
    New-MailboxDatabase -Name <DatabaseName> -Server <ServerName> -EdbFilePath <DatabaseFileNameandPath> -LogFolderPath <LogFilesPath>
  4. In the next step, set the attribute “This database can be overwritten by restore” with the following command.
    Set-MailboxDatabase <DatabaseName> -AllowFileRestore $true
  5. Now, move the database files like EDB, Log, and Exchange Search catalog files to the specified database folder that you have selected while creating a new database.
  6. Use the following command to mount the database.
    Mount-Database <DatabaseName>
  7. Once the mounting process of the database is complete, you’ll have to modify the user account settings using the Set-Mailbox cmdlet to ensure that the account points to the mailbox on the new server. You can use the below syntax to move all users from the old database to the new database.
    Get-Mailbox -Database <SourceDatabase> |where {$_.ObjectClass -NotMatch ‘(SystemAttendantMailbox|ExOleDbSystemMailbox)’}| Set-Mailbox -Database <TargetDatabase>
  8. In the last step, trigger the delivery of any message remaining in the queues with the following command:
    Get-Queue <QueueName> | Retry-Queue -Resubmit $true

Once the replication in Active Directory is complete, users can easily access their mailboxes on the new Exchange server. Usually, the users and clients are redirected to the new Exchange environment via Autodiscover. Also, Outlook web users will be redirected to the new Exchange environment.

To verify whether the mailboxes are successfully moved to the new Exchange Server, follow any of the below methods:

On opening any of these platforms, you’ll find that the mailboxes have been moved to the new Exchange Server.
